摘要： An apparatus received input of a base image and a reference image that are images picked up by two cameras provided on left and right. A window setting portion determines a size of a window based on an edge value of an image around a gaze point in the base image. A position deviation operation portion operates deviation between the image in the window of the base image and the image in the window of the reference image. A three-dimensional coordinate operation unit portion operates a three-dimensional coordinate of a surface of an object based on deviation between the images.

摘要： An authentication apparatus comprises a first acquiring part for acquiring three-dimensional shape information of a face of a target person to be authenticated, a compressing part for compressing said three-dimensional shape information by using a predetermined mapping relation, thereby generating three-dimensional shape feature information, and an authenticating part for performing an operation of authenticating said target person by using said three-dimensional shape feature information. When a vector space expressing said three-dimensional shape information is virtually separated into a first subspace in which the influence of a change in facial expression is relatively small and which is suitable for discrimination among persons and a second subspace in which the influence of a change in facial expression is relatively large and which is not suitable for discrimination among persons, said predetermined mapping relation is decided so as to transform an arbitrary vector in said vector space into a vector in said first subspace.

摘要： When a running vehicle moves backward and a right back portion of the robot, which is one end of it touches a wall, the robot is rotated to the left until a left back portion of the robot touches the wall. The angle of rotation .beta. at this time is measured and the value .beta./2 is represented by .alpha.. The robot is rotated to the right by the angle .beta.-.alpha.. Therefore, the robot is positioned perpendicular to the wall. Thereafter, the robot is moved backward until the back portion of the robot touches the wall. As a result, an apparatus for positioning the running robot relative to the wall is provided.

摘要： An autonomous vehicle capable of traveling and stopping parallel to a wall includes right and left driving wheels receiving driving force to be driven independently, a dependent wheel for supporting the autonomous vehicle together with the driving wheels for a straightforward movement and a U-turn, a motor for driving the right and left driving wheels, a coupling mechanism for transmitting the rotation of the motor to the driving wheels, an encoder for detecting the rotation amount and velocity of the motor, a gyro sensor for detecting the direction of the autonomous vehicle, a distance measurement sensor for measuring the distance to a right or left object of interest, and a controller for controlling the autonomous vehicle through the motor and the driving wheels. The controller receives the output of the encoder, calculates a control value for the driving wheels based on the rotation amount and rotation velocity of the motor, and determines that the autonomous vehicle travels parallel to the wall if the ratios of a time period to turn the autonomous vehicle rightward and a time period to turn the vehicle leftward in a prescribed time period are equal based on the control value.

摘要： A mobile robot control system with plural mobile robots each of which moves along a predetermined route in the same area. One mobile robot gives way to the other mobile robot when the mobile robot receives a signal emitted by the other mobile robot. A mobile robot moving on a predetermined route has a sensor which senses whether or not an obstacle exists on the route. The sensor senses again after a predetermined time from the first sensing whether the sensor still detects the obstacle existing on the route at the first sensing.
